摘要: A current injection diamond ultraviolet light emitting device comprising a high-quality diamond crystal and electrodes formed thereon, wherein carriers are injected by applying a dc voltage between the electrodes to cause light emmission by recombination of diamond free excitons. The diamond crystal is selected considering the photoluminescence spectrum and the half width of the Raman scattering peak inherent in diamond.

摘要: A current injection-type diamond ultraviolet light-emitting device is provided that achieves the diamond free exciton recombination radiation by forming electrodes on a high-quality diamond crystal and applying a DC voltage between both electrodes to inject carriers. A diamond crystal can be selected in terms of photoluminescent spectrum at room temperature and the half width of the Raman scattering peak intrinsic to the diamond.

摘要: A diamond high brightness ultraviolet ray emitting element employs the carrier high-density phase of a diamond as a light-emitting mechanism. It includes a diamond substrate (1), a first diamond layer (2) formed on the diamond substrate (1), a second diamond layer (3) formed on the first diamond layer (2) and functioning as an emission layer, a third diamond layer (4) formed on the second diamond layer (3), a first electrode (7) formed on the first diamond layer (2), and a second electrode (8) formed on the third diamond layer (4). The second diamond layer (3) constitutes the carrier high-density phase formed by high-density excitation. The combination of the high-density excitation with the high-quality diamond can implement the device that has stable carrier high-density phase, and emission efficiency higher than a conventional device with low-density excitation.
